sump light

I have a 39 gallon tank and now I'm adding a 20 gallon sump. What kind of light do I need? Plan to put live sand and rock and Algae in sump.

clip on, nuff said. those metal clip ons you can get at a hardware store, get a 5600k bulb or so. you only want to aim it at the refugium part because light in the intake or return pump chamber will cause coralline and no one wants a coralliney return pump. plus its cheap.

You do not need to put any light in the sump. The sump is used to hold all your equipment instead of having them inside the tank.

IF you plan to grow macro algae, then you will need a light in the sump. As stated above, you can use a simple clamp on light with an appropriate bulb. Make sure there is no chance for the light to fall into the sump.

Do you leave the light on 24 hours or just at night???

That depends on your needs. If you are experiencing diurnal changes in your pH levels, then by adding a light, timed opposite your display lights, will help to reduce or eliminate those swings. The diurnal changes in pH are common in reef aquaria and are result of changes in the level of CO2 in the tank. During the daylight hours, the process of photosynthesis converts CO2 into carbohydrate and oxygen. The lack of CO2 results in a higher pH. The respiration of organisms within your tank is constantly adding to the CO2 in the system, so at night, the CO2 levels rise, effectively reducing the pH. By adding the light to the sump at night, you allow the process of photosynthesis to continue in your refugium life throughout the nighttime hours, thereby continuing to keep the CO2 levels down, and subsequently keeping pH levels regulated.

If you have little in the way of diurnal pH swings, and are more concerned with the nutrient export performed by macro algae growth, then you might seek to keep the light on 24hrs.

and finally, if you have a sump with no refugium, then you have little if any need for a light on your sump. Except maybe to see to do your cleaning and maintenance.

Hope that Helps.

refugium

I do have a refugium. I build my sump out of a 20 gallon tank. skimmer-refugium to pump. In the refugium I added 4 pounds live rock and some Micro Algae with a plant light. Should I put some rubble rock or something in the hole where the water comes from the overflow into the sump. I have some Bio-Max made by Fluval left over from the other filter. Would this be ok to put in there??? Lots of bubbles in there. Sump has only been running but 1 day, but my water is not as clear as it was with the Fluval canitister filter. My tank is 5 weeks old.

sump

Not sure how much you can see. The line coming down from the aquarium is in the right back corner. Its in a 5 X 3" hole and has a 1" cap at the bottom. Water comes out there and at the top. Some goes to the skimmer and the rest pours in to the bubble trap to the refugium. I added another quart of water and that looks like it helped alot. I have a couple of float switches coming tomorrow. I'll rig that up and then I will not have to worry about the sump over flowing the tank. I'll just rig it were if for some reason the overflow stops you will get a low level in the sump and the pump will turn off.
